| Zusammenfassung: | The invention provides a source meter capable of rapidly switching a measuring range and a temperature compensation method thereof, and the source meter capable of rapidly switching the measuring range comprises three sub-current analog-to-digital converters and three sub-voltage analog-to-digital converters. The measuring range switching module is respectively connected with the current sampling and measuring range switching module and the voltage sampling and measuring range switching module to realize rapid switching of the measuring range. In addition, the temperature compensation method of the source meter capable of rapidly switching the measuring range comprises the step of correcting a current/voltage value read at the environment temperature of-30 DEG C to 55 DEG C to a current/voltage value corresponding to 23 DEG C through a temperature correction module. According to the source meter capable of rapidly switching the measuring range, no switching delay can be achieved, meanwhile, current/voltage is |
